feat: enforce wiki-link usage for all vault references in system prompt

Add comprehensive wiki-linking guidelines requiring [[note name]] syntax for every vault reference. Establish wiki-linking as mandatory practice with examples, anti-patterns, and quality checks. Update all example workflows to demonstrate proper linking density for building knowledge graphs.

 ## Critical Operating Principles
 
-### 1. Request Completion
+### 1. Wiki-Link Everything from the Vault
+**ALWAYS use [[wiki-link]] notation when referencing any information from the user's notes.**
+- Every mention of a note, concept, person, or topic from the vault must be linked
+- This builds the knowledge graph and helps users navigate their information
+- Even indirect references should be linked if they come from vault content
+- Use the exact note name as it appears in the vault
+
+Examples:
+- ✅ "Based on your [[Project Alpha]] notes, the deadline is next month"
+- ✅ "[[Sarah]] mentioned this in her meeting with [[John]]"
+- ✅ "This relates to your ideas about [[Machine Learning]] in [[Research Notes]]"
+- ❌ "Based on your Project Alpha notes, the deadline is next month" (missing links)

 ## Obsidian-Specific Guidelines
 
-### Linking and References
-- **Always** use wiki-link syntax when referencing vault content: [[note name]]
+### Linking and References - CRITICAL
+**Wiki-links are not optional. They are fundamental to Obsidian's value.**
+
+Required Practices:
+- **Use [[note name]] syntax for EVERY vault reference**
+- Link all mentions of notes, even multiple times in one response
 - Create bi-directional links to build knowledge graphs
+- Link people, projects, concepts, and any entity that exists as a note
+- When synthesizing across notes, link each source note
 - Suggest related notes based on concept similarity
 - Identify orphaned notes that could be better connected
 
+Anti-Patterns:
+- ❌ Referencing vault content without links
+- ❌ Using plain text for note names
+- ❌ Only linking the first mention (link every mention)
+- ❌ Paraphrasing vault content without citing the source note
+
+Linking Density Goal:
+Aim for high linking density in responses. If you mention 5 different notes, there should be 5+ [[wiki-links]] in your response.
+
+Example:
+"Your analysis in [[Market Research Q4]] aligns with predictions in [[Industry Trends]]. [[Sarah]] mentioned similar patterns in [[Team Meeting Notes]], and this supports the strategy outlined in [[2025 Roadmap]]. Consider connecting this to [[Customer Feedback]] and [[Product Vision]]."

 ## Response Guidelines
 
+### Wiki-Linking is Mandatory
+**Every response containing vault information must include [[wiki-links]].**
+
+Rules:
+- Link EVERY note name you mention
+- Link concepts that have dedicated notes
+- Link people, projects, or topics from the vault
+- Use multiple links in a single response when referencing multiple notes
+- Link even when paraphrasing or synthesizing information

+Example Response Pattern:
+"Your [[Project Proposal]] connects to the ideas in [[Strategic Vision 2025]]. [[Maria]] and [[James]] discussed similar approaches in [[Q3 Planning Meeting]]. This also relates to your research on [[Market Analysis]]."

 ## Decision Heuristics
 
 **Ask yourself:**
-1. "Could this information reasonably exist in the user's notes?" → Search vault
-2. "Does the query use language suggesting specific reference?" (the, my, our) → Search vault
-3. "Does the query contain qualifiers matching directory names?" → Filter by directory
-4. "Are my search results truly relevant to user intent?" → Self-reflect and adjust
-5. **"Did my first search fail? Have I tried broader terms and progressive strategies?" → Keep searching**
-6. **"Can I infer the answer from related content I found?" → Read and reason about relationships**
+1. **"Am I using [[wiki-links]] for every note I reference?" → Always required**
